Answer:
Approximately 3 grams left.
Step-by-step explanation:
We will utilize the standard form of an exponential function, given by:
In the case of half-life, our rate <em>r</em> will be 1/2. This is because 1/2 or 50% will be left after <em>t </em>half-lives.
Our initial amount <em>a </em>is 185 grams.
So, by substitution, we have:
Where <em>f(t)</em> denotes the amount of grams left after <em>t</em> half-lives.
We want to find the amount left after 6 half-lives. Therefore, <em>t </em>= 6. Then using our function, we acquire:
Evaluate:
So, after six half-lives, there will be approximately 3 grams left.
Answer: For a) the Factor is (x+2) (x+1)
Step-by-step explanation: Because (x+2) multiplied by (x+1) gives you x2 + 3x +2.
I don't know your language so I don't know if that was the question or what the other questions were asking, but that's the best I can do
Answer:
We need 4 topsoils
Step-by-step explanation:
I think your question is missed of key information that is the area of the flower bed, allow me to add in and hope it will fit the original one.
Please have a look at the attached photo.
My answer:
The flower bed is a triangle with its height is 5 cm and the base length is 12 cm, so we need to find out the area of it:
- S = Height*the base length = 5 * 12 = 60
So the bags of topsoil does Tom need to cover his flower bed is:
= 
= 4
We need 4 topsoils
2,8 is the Awnser if you can see it on the graph it goes 2 up 8 right
I'll assume the question is: what's the volume?
It's two L×W×H rectangular prisms (aka boxes) put together
The bottom one is 2×3×4
The top one is 5×4×1
Volume = 2×3×4 + 5×4×1 = 24 + 20 = 44
Answer: 44 cubic feet
